Damper absorbed energy vs cycle rate: how to avoid thermal failure
Damper temperature rise comes from absorbed energy per cycle times cycle rate. A three-step check for continuous duty: energy per stroke, heat power, allowed temperature rise - and when to size up.
Most engineers check only the absorbed energy per impact and miss the second key figure: heat power. A damper converts kinetic energy into heat; temperature rise is driven by energy per cycle times cycle rate - a correctly sized damper will still overheat if cycled too fast.
Three-step check for continuous duty: 1) keep energy per stroke within rating; 2) heat power = energy (Nm) x cycles per minute / 60, within the manufacturer continuous dissipation; 3) size up one step when ambient exceeds 30C. Twin-tube adjustable designs (such as the ACE damper series) carry more oil and surface, staying stable in continuous duty.
Overheating signs: housing above 80C, slower return or force drift - size up or slow the cycle. Absorbed-energy charts and cycle correction curves for models like the MC75M-1 are on the product pages.
When in doubt about thermal margin, send cycle rate, speed and moving mass to Juanmu for a duty-cycle check and recommendation.
